This was the best my slow grazing has turned up -- http://ampgarage.com/forum/viewtopic.ph ... 15#p241117.

Overall it was good thread for me to build understanding ahead of building.

Best .. Ian

Dunno if this helps, but here's a layout of the original version of the amp I built from the thread above.

I've since realized that I actually used a 1M for the master not 250k. I've made a bunch of changes to the amp since then, though.

Yes. It's actually using 2 v2 Belton bricks in parallel blending two differently filtered reverbs. Sounds great for always on reverb as long as you don't have the effects loop send cranked too high. I've actually moved over to a configuration where I'm using the loop return as another gain stage and the circuit as it stands can't handle that output level without distorting. Running it at 24 Volts gives the dry signal enough headroom, but the reverb signal still will distort. I plan on revisiting this circuit when I get a chance using the V3 brick, padding/recovering the wet signal and adding some dwell.

The treble pot in 102 when I worked on it was a mouser/alpha 250k linear that measured 236K. Before it was converted to a skyline EQ it would have had the fender 30% ish pot. The mid and bass pots were also Mouser, 250k 15%, and the bass pot measured 400K.
